Hugepd format is only used in PowerPC with hugetlbfs. In commit
a6e79df92e4a ("mm/gup: disallow FOLL_LONGTERM GUP-fast writing to
file-backed mappings"), we added a check to fail gup-fast if there's
potential risk of violating GUP over writeback file systems. That should
never apply to hugepd.

In order to support runtime timeslot route changes, some operations will
be different according the routing table used (common Rx and Tx table or
one table for Rx and one for Tx).
The is_tsa_64rxtx flag is introduced to avoid extra computation to
determine the table format each time we need it.
The Tx and Rx entries for a given channel are set in one function.
